The 2013 Buffalo Bills season was the franchise's 44th season in the National Football League (NFL) and the first under head coach Doug Marrone. It was also the final season under the ownership of Ralph Wilson, who died in March 2014 at the age of 95. The team equaled their record from 2012 and missed the playoffs, increasing their playoff drought to 14 seasons. This was the first year of renewed leases on Ralph Wilson Stadium and for the Bills Toronto Series, both of which were signed in the preceding offseason.
The 2013 season was the Miami Dolphins' 44th in the National Football league (NFL) and their 48th overall. The season concluded with the Dolphins finishing third in the AFC East division with an 8–8 record, and no postseason play for the fifth consecutive season. The Dolphins allowed a league-high 58 sacks.
The 2013 Cincinnati Bengals season was the franchise's 44th season in the National Football League (NFL), the 46th overall, and the 11th under head coach Marvin Lewis. The Bengals improved on their 10–6 regular season record from 2012 and clinched the AFC North division title. However, the Bengals lost 27–10 to the San Diego Chargers in the playoffs – the third consecutive season that the Bengals had lost in the Wild Card round. Their training camp was featured on the HBO show Hard Knocks.
The 2014 season was the Miami Dolphins' 45th in the National Football League (NFL), their 49th overall and their third under head coach Joe Philbin. Following the appointment of Dennis Hickey, the team had a new general manager for the first time since 2007 after Jeff Ireland was fired on January 7, 2014. The Dolphins equaled their 8–8 record from 2013 and missed the playoffs for a sixth consecutive season.
The 2014 season was the Baltimore Ravens' 19th in the National Football League (NFL) and their seventh under head coach John Harbaugh. The Ravens improved upon their 8–8 record from 2013, when they missed the playoffs for the first time since 2007. Additionally, the Ravens scored a franchise record 409 points and quarterback Joe Flacco passed for a career-high 27 touchdowns and 3,986 yards.
The 2015 Miami Dolphins season was the franchise's 46th season in the National Football League (NFL) and the 50th overall. The Dolphins looked to improve on their 8–8 record from 2014 and return to the playoffs for the first time in seven seasons. However, Miami failed to clinch a playoff berth for the seventh consecutive season after a Week 14 loss to the New York Giants.
The 2015 season was the Jacksonville Jaguars' 21st in the National Football League (NFL) and their third under head coach Gus Bradley. The Jaguars improved on their 3–13 record in 2014, finishing with a 5–11 record and winning their most games in a season since 2011. While they improved upon their previous two seasons, the Jaguars were eliminated from playoff contention before their Week 16 loss to the New Orleans Saints when the Houston Texans defeated the Tennessee Titans earlier in the day.
The 2016 Miami Dolphins season was the franchise's 47th season in the National Football League, the 51st overall and the first under head coach Adam Gase. The season saw the Dolphins trying to improve upon their 6–10 record from 2015. After a lackluster 1–4 start, the Dolphins would claim six straight wins, and finish the season on a 9–2 run. With their Week 15 win over the New York Jets, the Dolphins clinched a winning record for the first time since 2008, and clinched a playoff berth the following week after the Kansas City Chiefs defeated the Denver Broncos, ending their 8-year playoff drought. This made Gase the Dolphins' first rookie coach since Tony Sparano to end a year-long playoff drought and also lead them to a winning record of at least 10 wins. They were also the first AFC East team, other than the New England Patriots, to qualify for the postseason since the 2010 New York Jets. However, they were defeated by the Pittsburgh Steelers in the Wild Card round, ending their season and not winning a playoff game for the 16th straight year.
The 2016 season was the Baltimore Ravens' 21st in the National Football League (NFL) and their ninth under head coach John Harbaugh. With a week 12 win over the Cincinnati Bengals, the Ravens improved upon their 5–11 record from 2015, finishing the season 8–8. Despite the improvement, the Ravens failed to qualify for the playoffs for the second consecutive year after losing to the Pittsburgh Steelers on Christmas Day in Week 16. It was the first time the Ravens missed the playoffs in consecutive seasons since 2004–2005, and their first consecutive non-winning seasons since 1996–1999. They did, however, improve their position in the division, finishing in second place after finishing in third place for the previous three seasons.
The 2017 Miami Dolphins season was the franchise's 48th season in the National Football League, the 52nd overall and the second under head coach Adam Gase. The team came off from a 10-6 record and a playoff appearance for the first time since 2008. They were seen as potential playoff contenders and looked to make consecutive playoff seasons for the first time since the 2000 and 2001 seasons. However, the team was affected by the loss of starting quarterback Ryan Tannehill, who tore his ACL during practice and was ruled out for the season. The team turned to former Bears quarterback Jay Cutler, who came out of retirement to become Tannehill's replacement and team's starter. After Tannehill got injured, coach Adam Gase called former Denver Broncos quarterback Peyton Manning about possibly coming out of retirement and taking Tannehill's place. However Manning later declined the idea of coming out of retirement. Gase was the QB coach and offensive coordinator of Peyton's Broncos between the 2012 and 2014 seasons. Additionally, the Dolphins were also one of the teams Peyton considered signing with following his release by the Colts in 2012. Later during the season, the team traded starting running back Jay Ajayi to the eventual champion Philadelphia Eagles in exchange for a 2018 fourth round draft pick on October 31.
The 2017 season was the Baltimore Ravens' 22nd in the National Football League (NFL) and their 10th under head coach John Harbaugh. This was also the 10th season with Joe Flacco as the team's starting quarterback. The Ravens improved on the previous season's 8–8 record, but failed to qualify for the playoffs for the third consecutive season because of a last second touchdown in a 31–27 loss to the Cincinnati Bengals, combined with a Buffalo Bills' victory over the Miami Dolphins in Week 17.
The 2018 season was the Miami Dolphins' 49th in the National Football League, their 53rd overall and their third and last under head coach Adam Gase. During the offseason, the Dolphins tweaked their uniforms' orange color to better align with their classical past and history. For the second straight season, they also brought back their throwback uniforms from the Shula/Marino eras and wore them for three games.
The 2018 season was the New York Jets' 49th in the National Football League, their 59th overall and their fourth and final under head coach Todd Bowles. Despite starting 3–3, they lost 9 of their last 10 games. In Week 3, the Jets lost to the Browns by a score of 21–17, becoming the first team to lose to the Browns since the Chargers lost 20–17 on Christmas Eve 2016. The win by the Browns ended a 19-game winless streak. Week 6 marked the first season the Jets have scored 40+ points in multiple games since the 2008 season. They were officially mathematically eliminated from playoff contention for the 8th consecutive season after the Titans defeated the Jaguars 30–9 in Week 14. The Jets failed to improve on their 5–11 record from the previous season with a 38–3 blowout loss in Week 17 to the New England Patriots, finishing at last place in the AFC East with a 4–12 record. Following the season finale, the Jets fired Bowles.
The 2018 season was the Jacksonville Jaguars' 24th in the National Football League (NFL) and their second under head coach Doug Marrone. This was their first season in new uniforms, which were revealed in April 2018. The Jaguars had hopes of matching or improving on their 10–6 campaign from the year prior, but despite a 3–1 start, the Jags fell into a 7 game losing streak and failed to improve on their 10–6 record after a Week 10 loss to the Colts. After they lost to the Tennessee Titans in Week 14, the Jaguars fell to 4–9 and were officially eliminated from postseason contention. They finished 5–11, in last place in the AFC South.
The 2019 season was the Philadelphia Eagles' 87th in the National Football League (NFL) and fourth under head coach Doug Pederson. The Eagles acquired many key players, including wide receiver DeSean Jackson, running back Jordan Howard and defensive tackle Malik Jackson. With these offseason moves, the Eagles were listed as Super Bowl contenders. However, inconsistent play aided by injuries on both sides of the ball plagued the Eagles early in the year. Despite a 5–7 start, the Eagles won their last four games against divisional opponents and matched their 9–7 record from 2018. The Eagles clinched the NFC East division title, but were defeated by the Seattle Seahawks in the Wild Card round by a score of 17–9.
The 2020 season was the Jacksonville Jaguars' 26th season in the National Football League (NFL), their eighth and final season under general manager David Caldwell and their fourth and final season under head coach Doug Marrone. With a Week 11 loss to the Pittsburgh Steelers, the Jaguars dropped to 1–9 resulting in their third consecutive losing season and their ninth in ten seasons. After a loss to the Cleveland Browns in Week 12, the Jaguars both failed to improve on their 6–10 record from the previous season and were eliminated from playoff contention for the third consecutive season. They surpassed their loss total from the previous season after an overtime loss to the Minnesota Vikings.
The 2021 season was the Miami Dolphins' 52nd season in the National Football League (NFL), their 56th overall, and their third and final year under head coach Brian Flores, and sixth under general manager Chris Grier. Despite a 1–7 start to the season, Miami then won the next seven games, becoming the first team in NFL history to lose seven straight games and then win seven straight games in the same season. The 7-game win streak was their first since the 1985 season. They also became the sixth team in NFL history to win four or more consecutive games after losing seven in a row, after the 2009 Cleveland Browns, 1994 New York Giants, 1993 New England Patriots, 1984 Green Bay Packers, and the 1978 St. Louis Cardinals. However the Dolphins were eliminated from the playoffs for the fifth consecutive year after their win streak ended in Week 17 to the Tennessee Titans, combined with a win by the Los Angeles Chargers.
The 2021 season was the Atlanta Falcons' 56th season in the National Football League (NFL), their fifth playing their home games at Mercedes-Benz Stadium and their first under general manager Terry Fontenot and head coach Arthur Smith.
The 2022 season was the Miami Dolphins' 53rd in the National Football League (NFL), their 57th overall, the first under new head coach Mike McDaniel, and seventh under general manager Chris Grier. It also set out with the acquisition of 3x All-Pro receiver Tyreek Hill, who joined Jaylen Waddle as Tua Tagovailoa's receiving duo after breaking contract talks with the Chiefs and being traded in March.
The 2023 season was the Jacksonville Jaguars' 29th season in the National Football League (NFL), their third full season under the leadership of general manager Trent Baalke and their second under head coach Doug Pederson. With a Week 17 win over the Carolina Panthers, they matched their nine-win record from 2022. After starting the season with an 8–3 record, Jacksonville suffered a late-season collapse, losing five of their final six games, losing out on the AFC South division title to the Houston Texans, and missing the playoffs entirely after a Week 18 loss to the Tennessee Titans.
